In this lesson, you can learn about sentence structure in English.
You’ll learn how to construct all kinds of sentences in English, from the simplest possible sentences, to long, complex sentences that contain many different ideas.

Some verbs don't require an object, while others do. In this video, we learn when a sentence is complete, and when we need to add more words.

By adding a complement, we can form a complete sentence that is both grammatically correct and communicates meaning.

Using adjectives and adverbs, we can add detail and information to a basic sentence.

In this video, we learn how words called “conjunctions” are used to join two ideas to make one complex sentence. These parts are known as "clauses" and can be either independent or dependent.

A sentence can be formed from multiple independent clauses, and could in theory go on forever! But is this really a good idea? Olivier and Gina offer us some helpful guidelines.

This video will show you, in simple terms, the difference between an independent (or "main") clause and a dependent (or "subordinate") clause. It's important to remember than a dependent clause depends on the independent clause, and does not make sense on its own.

Relative pronouns such as “who,” “which,” or “what” can link two “relative clauses.” Gina and Olivier review what we have learned and give us some final tips on studying English sentence structure.
